(54)	Switch biasing member providing tactile feel

(57) A switch biasing member (20) is provided that features substantially transverse apposed resilient arm pairs (A₁, A₂) and (B₁, B₂) that extend from a support member (5) to respective preferably arcuately shaped spaced-apart free-ends (14, 14′) and (16, 16′) that are operative to engage an actuator (2) and impose respective forces (F₁) and (F₂) that respectively increasingly and then decreasingly appose movement of actuator (2) axially between two positions such that the combination of forces (F₁) and (F₂) provide a tactile feel to operation of actuator (2).
